OULDER-REST FOR GUN S.

Specification of Letters Patent. Patented June 14, 1921.

Application filed April 30, 1919. Serial No. 293,786.

(FILED UNDER THE ACT OF MARCH 3, 1883, 22 STAT. I, 625.)

To all whom it may com/em:

Be it known that I, SAMUEL G. GREEN, lieut, Ordnance Dept, United States Army, a citizen of the United States, stationed at Washington, 'D. (1., have invented an Improvement in Shoulder-Rests for Guns (Case B,) of which the following is a specification.

The invention described herein may be used by the Government, or any of its oflicers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any royalt thereon.

his application is a companion case to a copending application of mine filed May 7 1919, Serial N 0. 295,463.

The object is to provide a shoulderrest for machine guns in which the shoulder-restpiece may be quickly adjusted with reference to its support, to meet the requlrements of different operators; and has more particular reference to a shoulder rest embodying means for effecting such adjustment and for securing the shoulder-rest-piece to its support, somewhat different from the disclosure in my said companion application.

With this object in View, the invention resides, as generally stated, in a shoulder-rest embodying a tubular member slidable on and adapted to be secured to a member carried by the stock of the 11, said tubular member carrying at one en an apertured head; in a shoulder rest piece comprisin a member longitudinally curved to con orm to the curvature of the shoulder of the operator and carrying a tubular body slidable in said head; and in means for frlctionall clamping said tubular body to said hea against movement, after adjustment thereof.

The invention will be more'fully understood by reference to the accompanying drawings, in which like reference characters designate corresponding parts throughout the several views, which may be briefly described as follows:

Figure 1 is a view in side elevation of my shoulder rest;

Fig. 2 is a view in end elevation thereof;

Fi 3 is a fragmentary sectional view on the line 33 of Fig. 1, looking in the direction of the arrow;

Fig. 4 is a detail view, in end elevation, of the screw nut; and

for a portion of its length extending from.

one end thereof, and provided at the slit portion with a metallic strap 3, one terminal of whlch is bent to form a bifurcated loop 4 and the other terminal of which carries a hlnge 5 for a clamping bolt 6 adapted torest 1n the bifurcation of said loop 4. on the threaded portion 7 of the bolt is threaded a nut 8, whlch ma be screwed against the loop 4, thus tending to. contract the tube 1 and tighten the same around the extension of the stock of the gun.

Said tubular member and the means clamplng the same on the stock of a machine gun form no part of my invention.

The member 1, at the end thereof opposite the strap 3, carries a head 9 bored for the reception of a tubular slide 10, carrying an outward-projecting, longitudinally extending rib 11, having an arm 12 termlnating in feet 13, 13 secured to the lateral extension 14 of a shoulder-rest-piece 15. The rib 11 is also provided with flanges 16, 16 secured to said shoulder-rest-piece 15. Advantageously as shown, the tubular slide 10,the rib 11, the arm 12, the feet 13, 13 and the flanges 16, 16 are formed integral from a single piece of sheet metal. The blank after being out, is folded around a cylindrical mandrel, thereby forming the tube 10, and the remainder of the folded sections pressed flatly against or upon each other, thereby forming the web l112 projecting radially outward from the tube, longitudinally thereof.

The invention comprehends means for holding the tubular slide 10 in adjusted position. In this instance, I have shown in the drawings my preferred means, which I will now describe. Extending through the head 9 of the tubular member 1 at right angles to the opening 17 in which the tubular slide 10 slides, and intersecting said opening, is a second opening 18. Disposed in said opening 18 is a ring or washer 19 the side of which is beveled, as shown at 20, on the arc of a circle struck from the center of the tubular slide 10. The beveled surface of the ring 19, therefore, conforms to the curvature of the tubular slide-10, as shown in Fig. 3. Projecting through said washer or ring 19 is the shank 21 of a clamp ng bolt whose head 22 is provided with a similarly beveled portion 23 adapted to bear against the tubular slide 10. On the threaded portion 24 of the bolt is secured a nut 25, preferably provided with ahandle 26. In operation, it will be seen that, by screwlng up the nut 25 on the bolt 21, the head 22 and the washer 19 will be drawn toward each other, thus binding the tube 10 tightly agalnst the wall of the opening 17, thereby frictionally holding the slide 10 in adjusted position.

The head 22 and the washer 19 function as clamping-members, and it is obvious, of course, that while I have shown the clamping member 22 as formed integral with the shank 21, it may be separate therefrom and swiveled thereto.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A shoulder-rest comprising a member attachable to a un, a tubular slide extending through sald member and carrying a shoulder restpiece, and means passlng through said member 'for frictionally looking said slide in adjusted position.

2. A shoulder-rest comprising a member attachable to a un, a tubular slide extending through said member and carrying a shoulder-rest-piece, clamping members disposed interiorly of said gun-attachable member and adapted to bear against said slide, and means for causing said clamping members to bear forcibly against said slide.

3. A shoulder rest comprising a member attachable. to a gun, a tubular slide extending through said member and carrying a shoulder-rest-piece, clamping members disattachable to a gun, a tubular slide extend- I ing through said member and carrying a shoulder-rest-piece, clamping members disposed interiorly of said gun-attachable member and adapted to bear against said slide, 1

one of said clamping members having a threaded stem passing through the. other clamping member, and a nut threaded on said stem for causing said members to bear forcibly'against said slide. I

5. A shoulder-rest comprising a member attachable to a ing through said member and carrying a shoulder-rest-piece, said slide comprlsing a blank folded to form a tube with an integral web projecting outward from said tube longitudinally thereof, and a shoulder-restpiece secured to said web.

6. A shoulder-rest comprising a tubular member attachable to 'a gun and carr ing at one end, a block, a slide extending through said block and carrying a shoulderrestpiece, and clamping-mechanism projecting into said block for locking said slide in adjusted position.
